[0063] FIG. 8 is a first flow chart of a method for detecting body postures according to one embodiment of the present disclosure, as shown in FIG. 8, the method includes following steps:

[0064] Step S802, obtaining the first posture information and sending the first posture information to the processor 12 by the sensing device 11, and presenting the back posture changes of the body of the user by the first posture information.

[0065] Step S804, comparing the first posture information with the preset standard posture information by the processor 12, when the first posture information is greater than the standard posture information, generating the reminding signal and sending the reminding signal to the reminding device 13 by the processor 12.

[0070] Step S904, collecting second posture information according to the posture acquisition signal, and sending the second posture information to the processor 12 by the sensing device 11, and generating the standard posture information according to the second posture information by the processor 12.

[0071] Through steps S902 to S904, the user needs to set the standard posture information when initializing the posture detection device 10 during an initial use or during a use process. For example, during the initial use, the user is reminded through displaying or vibrations that current is an acquisition time of the standard posture information, so that the user sits upright, and the second posture information obtained by the sensing device 11 at this time is the standard posture information. Furthermore, postures of different users are customized to adapt to the different users, which improves the accuracy rate of detection.

[0072] In one embodiment, FIG. 10 is a third flow chart of a method for detecting body postures according to one embodiment of the present disclosure, as shown in FIG. 10, the method includes following steps:

[0073] Step S1002: after a first preset time period, obtaining third posture information and sending the third posture information to the processor 12 by the sensing device 11.

[0075] Through steps S1002 to S1004, the user may have some special application scenarios when the user uses the posture detection device 10, for example, the user bends over to pick up something. Therefore, it is necessary to adjust trigger sensitivity of the posture detection device 10. In normal work, after the reminding signal is triggered for the first preset time period, the third posture information of the user is obtained and compared with the standard posture information, a situation that the user's posture information temporarily and greatly changes in special scenarios is eliminated, and the reminding device 13 is prevented from being triggered by mistakes to start the one of the reminding modes.

[0076] In one embodiment, FIG. 11 is a flowchart of a sleep method of the posture detection device according to one embodiment of the present disclosure, as shown in FIG. 11, the method includes following steps:

[0077] Step S1102, obtaining fourth posture information, and sending the fourth posture information to the processor 12 by the sensing device 11.

[0078] Step S1104, comparing the fourth posture information with a first preset threshold by the processor 12, and when the fourth posture information is greater than the preset threshold, starting a sleep mode by the posture detection device 10.

[0079] Through steps S1002 to S1004, when the user uses the posture detection device 10, the posture detection device 10 may be removed and not used for a period of time, in order to prolong use time of the posture detection device 10 and save power, a situation when the posture detection device 10 is horizontally laid may be set, for example, when the first preset threshold is eighty degrees and the fourth posture information angle change is eighty-nine degrees, the posture detection device 10 is determined to be horizontally laid, and the posture detection device 10 starts the sleep mode, or after a horizontal state lasts for a period of time, the posture detection device 10 restarts the sleep mode, and the sleep mode is prevented from being triggered by mistakes.

[0080] In addition, in one embodiment, the posture detection device 10 only monitors spatial angle changes within a certain range when monitoring the hunchback, and the posture detection device 10 stops current monitoring work after the spatial angle changes are exceeded, excluding hunchback reminding when the spatial angle changes are close to ninety degrees or zero degrees, which also prolongs the use time of the posture detection device 10 and saves power.

[0081] In one embodiment, FIG. 12 is a flowchart of a step counting method of the posture detection device according to an embodiment of the present disclosure, as shown in FIG. 12, the method includes following steps:

[0082] Step S1202, obtaining fifth posture information and sending the fifth posture information to the processor 12 by the sensing device 11.

[0083] Step S1204, comparing the fifth posture information with a second preset threshold by the processor 12, and when the fifth posture information is greater than the second preset threshold, counting by the processor 12, and then presenting a number of steps of the user after counting.

[0084] The posture detection device 10 realizes a step counting function. When the sensing device 11 is the three-axis acceleration sensor, when the three-axis acceleration sensor monitors that the posture detection device 10 has a forward acceleration in the front direction corresponding to a human body and center of gravity changes up and down twice in the vertical direction and presents a certain periodic change, the certain periodic change is determined as an effective step in walking state, and the step counting function is realized by counting acceleration change peak values corresponding to the vertical direction of a human body. The step counting data is recorded and executed by the processor 12 to realize whole step counting algorithm. A debugging mechanism is set up in the step counting algorithm to ensure effectiveness of step counting. The debugging mechanism includes: one of the conditions for determining whether the user walks is to walk continuously instead of a single moving position, so changes of the center of gravity corresponding to the vertical direction of the human body are continuous and reach a certain number of cycles. Because fluctuation of walking is larger than fluctuation of activities such as riding in a car, a second condition is that the acceleration change peak values during process are higher than a particular value. At the same time, the fluctuation of walking is smaller than fluctuation of running, so a third condition is that the acceleration change peak values are also less than an another particular value. Because a limit of human walking speed and a limit of nerve reflection, a fourth condition is that intervals of the acceleration change peak values is to be within a certain time range. Step counting is used as an auxiliary function, and the posture detection device 10 may be used as a data collection terminal and sends statistical data to a connected mobile phone.
